I started potty training in 2.8 months, she is not 3 yr,still she is not able to poop in potty, she is afraid, avoiding potty, and when she wants to poop,she is asking for diaper, she has very much constipation, holds poop for 2 to 3 days, she is crying when sits in potty, .what medicine should be given during potty training, for motion to be flow, will she take more time to poop in potty??? I am very upset and mentally undergoing stress due to this...
